To ell whom it may concern Be it known that I, THOMAS S. .Wanivnn, acitizen of the United States of America, and

resident of Springfield, Ohio, have invented example, by my improvedlister cultivator,

a certain new and useful Improvement in Cultivators, of which thefollowing is a specificatio My invention relates to what are commonlyknown as lister cultivators-that is to say, machines adapted tocultivating corn that ha been planted in trenches by means of a lister.The prior art is exemplified, to

some extent at least, in PatentNo. 701,972.

My present invention contemplatescertain improvements on the listercultivator of the general type disclosed 1n said patent. For

them from the in-throw to the out-throw with or. without interchangingthem and with or without disengaging them from their mountings orbearings. This Ifind to be of considerable advantage, as it simplifiesand :lacilitatesthe operation of changing the disks from the iii-throwtothe out-throw, or from the out-throw to the iii-throw, according tothe requirements of the work for which a cultivatorof thisparticularcharacter designed. rigainl provide improved means for varying theangularity and slant of the cultivator disks, whereby such adjustmentcan be accomplished readily and according to the character of the work.Also, by my improved construction, I providemeans for raising andlowering the cultivator disks independently of the shovels, as well asmeans for raising and lowering the shovels independently of the disks.As

" will hereafter more fully appear, however, andby reason ofatoggle-llke connection beit tween the wheelsand frameyof the cultivator,the, raising of the cultivator disks tends also togive the entirecultivator, except the Specification of Letters Patent. Patented Aug,25, Application filed October 31, 1908. Serial No. 460,417. r 1

wheels of course, a slight bodily an or upward motion and at the sametime tovary the balance, thus relieving the neck weight J of the pole.

I provide a couple of hand levershavinglan interlocking connectionbetween them, whereby the raising and lowering of the shovels can bemade to accompanythe rais-I ing and lowering of the disksby simplygrasping and operating the lever which is allotted to the said disks.With this arrangement, I find that the control ofthe cultivator in thefield is greatly facilitated and improved. 1

Still another featureof improvement con sists in the provision. ofhaso-called hard As still another feature of improvement,

oiler for the cultivator disks, which disks 1 are arranged forinstantaneous adjustment. from the' nrthrow and out-throw, and viceversa, as previously explained.

my invention consists in matters hereinafter set forth and claimed andillustrated inthe vention, the cultivator disks and shovels bein shown.resting on the ground. Fig. 2 a similar:view showing the disks andshovels raised from the ground. Fig. 3 is a plan. of the said listercultivator, it being ob served thatthe disks and shovels are set for thein-throw. Fig. 4 is a rear view of the said lister cultivator, showingthe plank or connecting beam which is employed for con v nectmg suchcultivator wlth another similar cultlvator, 1t :belng understood thatthese cultivators are usually employed in .pairs, one being left-l1andedand the other righthanded, and that the driver occupies the seat whichis supported on the said plank To the foregoing, andother usefulends,

or connecting beam on the point midwaybetween the two cultivators, thusbringingthe driver into a position to manipulate the hand-levers of bothcultivators. Fig. 5 1s an enlargeddetail view of one ofthe mountlugs forthe wheel and diskon one side of.

the cultivator. Fig. 6 is an enlarged detail 105. view illustratlng theconstruction for changin the horizontal an 'ularit or slant of one b b uof the disks. Fig. 7 is an enlarged sectional view of one of the dlsksshowing the improved hard oiler forthe same. .Elg. 8 is an 11o enlargedCITOSS SQCtIOD .onthehne 8--8 of i Fig. 7. Fig. 9 is an enlarged sectionlongitudinally of the squared shaft upon which the shovels are mounted,and which carries the arms or lifting connections by which the disks areraised andlowered. Fig. is a detail perspective view of the portion ofthe said square shaft showing means by which the arm is operated toraise and lower the shovel, and showing a portion of the arm which isloose on said shaft and by which the disks are raised and lowered. Fig.11- is a detail view showing the squared shaft in cross section andshowing the bearing in which the same is adapted to turn or rock.v Fig.12 is a detail view showing the bottom of one of the'clamps or mountingsby which the shovel beams are secured to' the said squared shaft whichlatteris in the nature of a rock shaft. Fig. 13 is aview .similar toFig. 3, but showing the disks and shovels reversed or adjusted in aposition for the out-throw that is to say, the adjustment by which thedisks throw the oirt outwardly rather than inwardly.

' As" thus illustrated, my invention coin-- prises a tongue A, to whichare rigidly secured the side members 'or frame bars B. A transverse axleG is mounted in suitable bearings on said tongue and side bars, and asquared rock shaft D is mounted in the bearings secured to the ends ofsaid bars B. The disk-like wheels E are mounted upon the lower ends ofthe spindles or arms 6, and the latter have their upper ends hung inswinging castings or arms 6 which latter in turn hung on the said aXleC. The said castings are provided with bifurcated upper endportionsbetween which are arranged the bearings e by which the said axle issupported on the frame. v With this arrangement the castings or swingingarms 6 can be moved toward and away from each other on the said axle. Inorder to hold the saidcastings or arms in dif erent positions on thesaid axle theupper ends of the same are provided with openings 6 adaptedto receive the collars e" which are secured on the aXle with set screws6 In this way the said castings or: arms 6 are held against movementtoward and away from each other, and at the same time left free to swingupon the said axle;- Brace rods 6 connect the lower ends of the wheelspindles 6 with the tongue A, so as to'hold the wheels in position tosupport the tongue and frame and other parts in asuitab'ly'elevatedposition. Itwill be seen that the spindles e and thecastings or arms e-are pivotally connected in sucn manner that each wheel spindle and itsallotted casting form a toggle joint connection between the culti vatorframe or body and the supporting wheel E.

The angularly disposed cultivator disks F' are mounted upon spindleswhich are rotatably carr ed or inserted in the lower end portions f thecastings 6 It will be seen that eaclrspindle consists of a lower endsecticn f and an upper section P, the two sections being pivotallyconnected together by a bolt f and a collar f*, which latter is clampedon the spindle section f Another collar f is clamped onthe section f andthis collar is connected with the spindle section 1 by means of a rodf". In this way the angular relation of the two sect-ions can be changedor varied as shown in Fig. 6,by sliding" the collar f back and forthon'the spindle section f. This, offcourse, will change the horizontalangularity of the cultivator disks, so that they may work according todifferent requirements. 1 In order that each disk may be oiled by hardoil or grease, these spindle sections f are preferablyprovided with alongitudinal groove f and the end is threaded to receivea threadedgrease cap The sleeve f of the disk extends for some disengages from thethreaded portion of the hub f, as shownin F 1g. 7. This leaves the diskin position to turn freely, and the caps The hub f of the Thus when thecap f gis screwed in f of the two disks are held against turning by thesupports or'brace rods f. f are loosely'mounted on the rock shaft D andconnected together by a bar f to which the upper ends of the rods f aresuitably secured. rin arch or arm 1"" connects the bar f with the rockshaft D,'being loosely mounted on the latter. Theshovels G are securedto beams 51, which latter are rigidly secured near the. outer ends ofthe rock shaft D, in such a way as to allow a lateral adjustment, bymeans of which the d1stance between the shovels can be varied.Preferably,'the said shovel beams g are secured to the rock shaft bymeans of clips 9 which latter have 'c' rossgrooves 1 adapted to beengaged by theend portions of said shovel beams, insuch' a way that aforward or backward adjustment fof the beam will give Thearms a lateraladjustn ient to the shovel. In F i 3 it will be seen that these shovelbeams converge toward the rock shaft, while in Fig. 13 the saidshovel'beams converge rearwardly.

These shovelbeams are interchangeable, and

it is the crossed grooves g? which accommodate the sa d beams 1n theirdifferent positions on the bottom of said clips. In this way the shovelscan be made to trail behind the cultivator disks in the usual manner,and for the well known purposes, re ardlessof the distance between thesaid disks. In Fig. 3 the disks and shovels are set forithe inthrowwhile in Fig. 13 the same are setfor whee the out-throw. In Fig. 13 therods f are shiftedinto engagement with the bracket f located centrallyof the bar f. In this way the disks are supported in either position andthe change is made by simply swinging the disks over from one positionto the other, the spindle of each disk being rotatably mounted in one ofthe castings 0 Any suitable means can be employed for holding thespindles 0f the disks against endwise displacement in the bearings Thewheel spindles e are held against displacement from the said castings bymeans of collars c secured to said spindles and held inplace bysetscrews 6 said castings being each provided with a cavity or opening 6to accommodate said collar, as shown in Fig. 5. The brace rods H havetheir forward ends pivotallyconnected with the castings a and theirrear-ends pivotally connected with the brackets it carried by the armsf. In this way the raising and lowering of the arms f not only tends toraise the cultivator disks f, but also tends to manipulate the toggleconnections between the wheels E and the frame of the cultivator, thusslightly raising the said frame on the said wheels when the disks areraised from the ground and shifting the is under the cultivator, therebychangingthe balance. i

,In order to rock the rock shaft ,1) and thereby raise and lower theshovels G, the said shaft is provided witlran arm I, which latter isconnected by a rod t with a hand lever '5 On this rod there is a loosesleeve which is secured to the said arm I and which is prevented fromsliding oil the end of the rod bythe pin 2'. A collar 2' is secured tothe said rod, and a spring 15 is interposed between this collar 1 andthe sleeve In this way the shovels are yieldingly held in the ground,and are free to yield to obstructions and rise against the pressure ofsaid spring. The said hand lever 71 is provided with asuitable handoperated latch or locking device adapted to engage a rack or segnent Jwhich is secured to a second hand lever j. This second hand lever is inturn provided with an ordinary hand operated latch or locking deviceadapted to engage a stationary rack or segment j which latter is mountedon the tongue o-tthe cultivator.

It will be understood that both hand levers are suitably pivoted at.their lower ends so I that they may be swung forward and back by thedriver or operator whooccupies the seat K. A red F connects the lever jwith the arm or arch f, so as to raise and lower the shovels G and disksF when the two hand levers are locked together. It will be seen,however, that the hand lever i can be operated independently of theother lever forthe purpose of raising and lowering, the shovelsindependently of the disks. On the other hand if necessary, the handlever i can be held stationary while the other lever is manipulatedtochange the positions. of the it Will be seen that the two hand leversare inclined to the right, so as to be within reach of the driveroccupying the scat K. This seat, it will be seen, is mounted on thecross plank or beam d? which extends from one cultivator to the other,it being common practice to employ these cultlvators in pairs.

The cultivator shown, is a left-hand Ina- Cl1ll'1t3,{t11l the plank orbeam would eX- tend over to the right hand cultivator, the hand leversof which latter would incline to the left and thus be within reach ofthe driver. "It is a matter.ofconimon knowledge that in using acultivator of this particular type it is desirable at one time to havethe disks set tor an iii-throw oi the end, while 75 i from the ground.By referring to Fig. 4t

at other times and for another part of the general work of thisparticular kind of cultivating it isdcsirable tohave the said disks setfor an out-throw Off are soil. as pre viously explained, my improvedcultivator disks are adjustable from the iii-throw to the out-throw,simply byswinging each disk over fromone position to the other. The

shovels which trail behind the disks are always, of course, adjustedaccording to the distance between the disks, and this is done byinterchanging the shovel beams, as pro. viously explained. It is evidentthat the said shovel beams can be interchanged, and thus shifted fromone clip to the other. On the other hand, the clips themselves can beloosened. in order to take oil the shovel beams and the beams With theirclips still attached can then be interchanged so that the clips aretransferred from one end to the other of the rock shaft 1) upon whichthey are mounted, Thus considerable latitudeof adjustment is given forallfpurposes; and in each oz se the adjustment or change is eil'ectedquickly and by exceediitigly simple and eil'ective means. constructionof the cultivator isboth strong and light, and the parts are wellbalanced At the sanie tiinc the its llli i with respect to thedillierent strains to which the cultivator is subject while in use.

1th further respect to the changing oi.

the disks from the in-throw to the outthrow,

and vice 'versa, 1t Wlll be seen. that such adjustment can bettCClJiIlPliSllGCl by interchang 7 ing the disks and theirjointedspindles that is to say, by :trans'terring one entire spindle andits disk itroin one castingc" to the other casing 0 For certain requireCri ments and in some situations, this may be found desirable, althoughfor ordinary purposes the disks are changed from one position to theother by simply swinging them over, and without removing their spindlesfrom the said castings. In any event, however, the disk spindles arepreferably supported by hanger rods or braces f, as explained, and thesebraces or hanger rods may be applied in various ways without de- Thiscan be done, as stated, by either interchanging the spindles, or byrotating the same in their bearings on the lower ends of the castings 0according to. requirements. The constructioncan of course, be changed.or modified more or less in order to accomplish these and other similarmethods of adjustment without departing from the spirit of my invention.As shown, the hangers or brace rods f are secured at their lower ends tothe caps f by means of threads, in such a way that the braces can bemade shorter or longer thus changing the vertical angle or slant of thedisks, and thus preventt 1e latter from turning and hold thedisksrigidly to their work. V iththis arrangement the said hangers orbrace rods are in the rear of the disks, but it is obvious that they maybe otherwise located, relative to the disks. For this reason I do notlimit myself to the exact construction of arrangement shown anddescribed. At their upper ends the hangers or brace rods i are securedto the cross bar f, in one of several positions, by means of a series ofholes, thus securing ad ditional adjustment for depth of disks. l Vhat Iclaim as my invention is:
